In the example below, the address line 1 is in column D and address line 2 is in column E.
  1. Insert two new columns into the spreadsheet after the column with the second address line. These will be columns F and G in the example.
     
  2. Highlight cell F2 (the first address line)
     
  3. Select Insert, function from the menu bar
    NOTE: In Office 2007, the 'Insert Function' button is under the Formulas tab across the top
     
  4. Select All as the Function Category and Concatenate as the Function Name
     
  5. In the Text 1 field of the Concatenate window, type D2 (cell containing address line 1)
     
  6. In the Text 2 field, type /n
     
  7. In the Text 3 field, type E2 (cell containing address line 2)
     
  8. Click OK
     
  9. Copy the function from cell F2 all the way down column F

    NOTE: This should be done only for records that have a second address line. If all addresses do not have a second address line, first, sort the spreadsheet by column E (e.g. the column with the second address line). Those records with two address lines appears at the top of the spreadsheet. When copying the function, copy it to those records with a second address line.
     
  10. Highlight cells F2 through Fx where Fx is the last cell in column F with information
     
  11. Select Edit, Copy from the menu bar
     
  12. Click in cell G2 (the second blank column added in step #1)
     
  13. Select Edit, Paste Special from the menu bar
     
  14. In the Paste section of the Paste Special window, mark Values
     
  15. Click OK
     
  16. Delete columns D, E and F (address line 1, address line 2, and the original formula)
     
  17. Type AddrLines as the header for the new column D (the final combined address lines column)
     
  18. Select File, Save from the menu bar
     
  19. Give the file a descriptive name and select CSV (Comma-delimited) as the format

NOTE: Even though the carriage return will not reformat the concatenated cell, it will import correctly.
